AMD HD3D and Dirt 3

[sl4y3r]

I Recently purchased a 55" LG 3D TV and read Dirt 3 supports Native 3D on AMD devices that feature HD3D. My Gfx (HD6870) does support HD3D. But i dont see any option in the Graphics options to enable it. Does it need a patch or something ?Thanks.

If, and this is a big if, your 3D TV has HDMI 1.4a (and I mean 1.4a), then you'll need to get Tridef or iz3d software. The software will enable support.

I suppose it is possible that you won't need the software for that game only, but you still need an HDMI 1.4a connection.

The TV does have HDMI 1.4 , Its connected via a A/V Recieved that is 1.4 3D enabled too.Yet no option.The AMD site says for Dirt 3 DDD or Tridef is not required as it has Native 3D support.

HDMI 1.4 will not work. It must have that "a" at the end. HDMI 1.4a or displayport are required for AMD HD3D.

Im not sure if its a of what... Assumed if its a 3D TV and 1.4 was the highlight of HDMI 1.4 it should work. Power DVD 12 auto detects my TV as a 1.4 Enabled 3D tv, cant remember if it had the "a" , Im at work so lets assume it is 1.4a any idea where I'd see the 3D option in the game?

bystander have you ever run Dirt 3 in native 3D on a previous setup(Since your current setup has a 680) ?

Most HDMI 1.4 are not 1.4a compatible. If there is no a, it is not compatible.

No. I did run DA:Origin, Metro 2033 and Crysis 2, but not Dirt 3 (I do have the game, but didn't try it).

Just a post back to give the outcome over the weekend, Dirt 3 DOES require the 1.2 patch for one to see the Stereoscopic Render option in the graphics menu.(Will be greyed out if it doesnt detect a compatible display) I however was able to enable it , but Its a hit on performance and drops my TV to 24hz and my audio goes away. I got stereo option by default in Dirt Showdown.

That must mean that your TV does have HDMI 1.4a. You can play it at 720p and get 60hz.

Is 3D @ 1080p locked to 24hz ?

It used to be. It's not about 3D, or the display itself, but HDMI cannot send enough info to support 60hz in 3D at 1080p. However, I believe the newer drivers from AMD were supposed to allow you to get 30hz at 1080p using HDMI.
